Ojousama, Otona no Kiss no Ojikan desu

For my first, I was taken by my butler. Nene who attends a young lady's school has a one-sided love for Sakuma, her butler. But, she was told on her 17th birthday that she is to marry someone one whom she has never met before. Even so, not giving up on Sakuma, she asks of him to teach her about dirty things. If he does so, will she be french-kissed, or even more? A highly thrilling and stimulating love story.
